Definitions

  • the invention relates to a method for establishing a communication connection in a communication network consisting of several networked switching nodes and an address converter to support the connection establishment.
  • Communication networks consist of a plurality of interconnected switching nodes to which communication terminals can be connected directly or via further devices.
  • Examples of such communication networks are the public switched telephone network (PST), data networks or also mobile radio networks, such as the GSM mobile radio system (Global System for Mobile Communications).
  • PST public switched telephone network
  • GSM Global System for Mobile Communications
  • a participant in one of these networks has a communication terminal and wants to establish a communication connection to a second communication terminal. To do this, it is necessary to dial an operator-specific number in the communication terminal. This operator-specific call number serves the switching nodes as addressing information for the second communication terminal.
  • the invention is therefore based on the object of specifying a method and an address converter which make it easier for the calling subscriber to establish a communication connection to another subscriber.
  • This object is achieved by the method according to the features of patent claim 1 and solved by the address converter according to the features of claim 12.
  • Advantageous further developments can be found in the subclaims.
  • first address information is transmitted from a first communication terminal to set up a communication connection to a first switching node, first identification features being contained in the first address information.
  • the first switching node evaluates the first address information with the first identification features and derives therefrom a second address information for addressing a first address converter. At least parts of the first identification features are transmitted to the first address converter. From the first identification features, second identification features are generated, which are used to address a second switching node. With the second identification features, the communication connection between the first and second switching nodes is established.
  • the method according to the invention enables the connection to be established even in the case of incomplete address information in the sense of operator-specific call numbers. Equal opportunities between operators of different communication networks are also increased, since even subscriber-specific information without precise network knowledge is sufficient to establish the connection.
  • the first address converter determines from the first identification features the address of a responsible second address converter which generates at least parts of the second identification features after appropriate signaling.
  • this makes it easier to specialize the address converters for certain functions, since not all of the first address converters have to have a complete data set available for address conversion.
  • SCP service control point
  • a plurality of second address converters are arranged in the communication network according to subscriber-classifying criteria.
  • participant-classifying aspects are, for example, certain services (Fleurop, emergency service), certain industries (hotels) or certain groups of participants (Siemens employees, residents of a district). This makes it possible for independent providers or operators to provide better accessibility for such services, industries or groups of participants.
  • the first and / or second address converters are designed as devices for different subnets of an overarching communication network or as independent units in the sense of intelligent networks. These address converters serve as a bridge between the networks when addressing. The extended addressing can be offered more economically if it is made accessible to the calling subscribers of several communication networks.
  • the second identification features advantageously contain operator-specific phone numbers or subscriber addresses. With these second identification features a direct connection establishment is possible without further format conversion.
  • the first identification features contain, for example, addresses or vehicle registration numbers of the participant of the second communication kationsendilless, or other easily memorable characteristics for a person.
  • the structure of the first identification features should ensure a quick selection of the address translators and a sufficiently good restriction for a search algorithm.
  • An advantageous embodiment of the invention provides that the first or second address translator transmits the second identification features to the first switching node for establishing the communication connection.
  • This means that the function of the address translator can essentially be limited to translating the addresses and possibly manipulating the data entries.
  • the address translators are therefore easy and inexpensive to implement and can also be used universally.
  • a subscriber can advantageously change the identification features of the communication terminal assigned to him. This gives the subscriber the opportunity and the responsibility to define himself with which identification features he can be reached or he usually has address conversions carried out for an outgoing call.
  • the rigid assignment of the communication terminal and the operator-specific phone number is removed and there is still more room for maneuver. For example, for advertising campaigns or similar a special assignment can also be defined at short notice.
  • a further advantageous embodiment provides that the number and / or the length of the first identification features are classified for a subscriber.
  • the participant is therefore given a limited and gradually expandable design scope, which can be combined with predetermined fees.
  • the service according to the invention can thus be introduced in stages and allows gradual adaptation to the needs of the subscriber. If this number or length is exceeded, a change in the first identification features blocked for the participant. This avoids bypassing the limited scope for design.
  • the method according to the invention allows the conversion between different address types, for example between telephone numbers and e-mail addresses.
  • a format error is determined by the first switching node when evaluating the first address information, a fixed address translator is automatically used to evaluate the first address information. Format errors do not result in the connection being terminated, but can be served by an address converter that can be individually defined for each switching node. According to this development, the switching nodes do not need to be converted for a selection of a suitable address converter.
  • the first and / or second address converter informs the first switching node or the first communication terminal of missing identification features.
  • the subscriber is thus informed about problems in establishing a connection.
  • the missing identification features are advantageously transmitted from the first communication terminal and / or the first switching node to the first and / or second address converter.
  • Valid identification features can be generated in the form of a dialog.
  • the implementation of the method is simplified if a first identification feature contains a character for a subsequent incomplete first address information.
  • the first communication terminal already specifies to the first switching node that an address conversion is necessary. This measure replaces the detection of format errors in the switching nodes.
  • An advantageous application of the method is a mobile radio network, parts of the second identification features describing the address of a home register and the second communication terminal. In addition to the identification of the second communication terminal, this also makes it fast
